Are RAM cleaners like minimem and cleanmem safe or potentially destructive? I have Windows 7 32 bit OS and one gig of RAM installed, and I know this isn't much but my computer runs slowly, very slowly, when I try to listen to Rdio, Pandora, youtube, talkradio or other audio, sometimes even without streaming audio (this wasn't the case until recently). Computer has been fine up til this point and I'm thinking of trying RAM cleaner
